#7713: Panic! make_exp (App _ (Coercion _)) when compiled with -fext-core ---------------------------------+------------------------------------------ Reporter: EduardSergeev | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.2 Keywords: -fext-core panic | Os: Linux Architecture: x86_64 (amd64) | Failure: Compile-time crash Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | ---------------------------------+------------------------------------------ Comment(by mvanier): I got the same compiler panic with ghc 7.4.2 on Mac OS X 10.6.8 with this trivial file: {{{ -- Begin file "Main.hs". -- Compile with "ghc -fext-core Main.hs" module Main where main :: IO () main = print 10 -- End file. }}} Curiously, it doesn't panic when the `main = print 10` line is changed to `main = print "10"`. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7713#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
